The Metric System Scientific data is always reported using metric system units of measurement. There are four basic metric measurement units: • Length = meter (m) • Volume = liter (l) • Mass (weight) = gram (g) • Temperature = ° Celsius (° C) All four metric system basic units can be converted into larger or smaller units simply by adding a prefix in front of the basic unit: Unit prefixes: • kilo (k) = Makes the basic unit 1000 times larger (103) • deci (d) = Makes

Unlike today‚ where most scientific communities use the standard unit of measurement called the metric system‚ early measurements were based on human body parts. In time‚ nations developed their own different units of measure. Due to all the different national measurements‚ it was difficult for scientists to understand each other‚ resulting in chaos. For example‚ if the United States conducted an experiment and France wanted to mimic the experiment‚ the different units of measure would make the

Lab 2: The Metric System and Microscope Name _________________________ Date __________________________ Section 1: The Metric System The Metric System is known as the International System of Measurement. The Metric System is based on Standard-prefixes that correspond to ‘multiples of 10’. The measurements of volume (the liter)‚ mass (the gram)‚ and length (the meter) are the baseline for all metric unit conversion factors. In the United States‚ the English System is more commonly used;

The United States Should Switch to the Metric System One crucial‚ yet widely unnoticed issue plagues the United States of America today: the country simply faces a stubborn unwillingness to convert to the metric system. America spends millions of dollars on keeping the U.S. customary system in place. The refusal to convert hinders the country’s progress in the global economy. A conversion failure even sent a poor satellite hurtling towards destruction on the surface of Mars (Wheeler). The United

Why isn’t the metric system used more prominently in the United States? Since I was a child‚ I can remember the disagreements among school boards in the early 1970’s about transition my school to the metric system. It was a voluntary transition and many school did not want to implement it. When I was n elementary school the opposition came from the parents believe it or not. They said they would not be able to help their children with homework‚ etc. Actually looking back on it‚ parents did not

Should the United States adopt the SI units/metric system or keep the American standard system? This is a question that has been arising since the invention of the metric system in France‚ 1790. Thomas Jefferson‚ president at the time of the invention‚ was deciding whether to adopt the system at the time in which he included on the constitution. I think that the metric system should be adopted in America‚ not only to please others‚ but to benefit us. The SI units are easier to use‚ would be more

Ryan Marsden Block 4 – AP English Metric Conversion: Weighing Pound for Pound In 1960‚ the Treaty of the Meter approved a modern draft of the metric system‚ Le Système International d’Unités‚ or the International System of Units‚ abbreviated SI. This system was designed to allow countries to trade on a unified system of weights‚ lengths‚ and other forms of measurements. The United States was committed to unorthodox measurements such as feet‚ pounds‚ and gallons. All unstandardized‚ the American
